21  Bitcoin / Mining speculation / Re: Can I find 1 BTC? on: January 23, 2017, 02:10:23 PM
You'll never FIND 1 btc except somebody will hand you over a wallet with 1 btc. Otherwise type in google "bitcoin mining", read for a bit, and come later with some wiser questions.
22  Bitcoin / Mining speculation / Re: What is the average loss of profit in mining? on: January 23, 2017, 01:59:27 PM
the average increase per month for the diff was estimated around 10%, and up to 20% on some months

but it also vary in comparison to the value, it may increase or decrease farthur

For example, when I calculate for 11 TH/s the first month is 0.24989525 BTC the second month is 0.22547303 BTC BTC.

(0.22547303 / 0.24989525) * 100 = 90%

As you say, about 10% is lost. On average, let's assume the lost value is 15%.

Month 1: 0.24989525 * 0.85 = 0.212410963 BTC ~ 189,8 USD
Month 2: 0.212410963 * 0.85 = 0.180549318 BTC ~ 161,4 USD
Month 3: 0.180549318 * 0.85 = 0.15346692 BTC ~ 137.2 USD
Month 4: 0.15346692 * 0.85 = 0.130446882 BTC ~ 116,7 USD
Month 5: 0.130446882 * 0.85 = 0.11087985 BTC ~ 99,23 USD
Month 6: 0.11087985 * 0.85 = 0.094247872 BTC ~ 84.34 USD
Month 7: 0.094247872 * 0.85 = 0.080110691 BTC ~ 71,54 USD
Month 8: 0.080110691 * 0.85 = 0.068094088 BTC ~ 60,81 USD
Month 9: 0.068094088 * 0.85 = 0.057879974 BTC ~ 51,70 USD
Month 10: 0.057879974 * 0.85 = 0.049197978 BTC ~ 43,93 USD
Month 11: 0.049197978 * 0.85 = 0.041818281 BTC ~ 37,35 USD
Month 12: 0.041818281 * 0.85 = 0.035545539 BTC ~ 31,75 USD

189,8 + 161,4 + 137,2 + 116,7 + 99,23 + 84,34 + 71,54 + 60,81 + 51,70 + 43,93 + 37,35 + 31,75 = 1085, 75 USD

The price of the antminer device is 1232 USD Also electric, cooling etc. There will be extra costs such as.
If the device works for 1 year without any malfunction, it will save 1085.75 USD.
Mining does not look very profitable. Is there a mistake in my calculations?

What you need to understand is that there is such a notion as "yield per TH/s". This one is for sure will decrease over time in btc, but in fiat it tends to stay the same (at least for half of the year as I've been mining and not including such events as halvings). The math you did has a pretty high chance of becoming real except for the last part of it, where your btc price is fixed and therefore it is less likely to turn out as you wrote (once again for the FIAT part).

If you believe in bitcoin and that its price will keep rising, than you are probably looking at decrease in fiat profit from $190 to $150 or so over this period of time. If you don't believe in it, then the math you did has a chance (maybe a little, but still) that btc price won't go higher than 1k during this year and your overall profit will be negative. Once you've chosen your side you can decide whether or not mining is for you Wink

Bitmain has probably launched the data-center that was announced at the end of 2016. And if btc price doesn't reach $1k in the nearest future, then mining profits will start to actually decrease...

dude, those new ones were sold at 291 USD (official bitmain price) and now you ask even more for the used ones? I could understand this kind of logic if you were selling them on ebay, but it's btctalk, where people mostly know what they buy and how much it really costs. If delivery wasn't a problem I would give this unit ~250 USD as a fair market price.

Since when are miners ever "fairly" priced? Either used or new.


since market with buyers and sellers of those ones exists

1) Can you tell why are you selling these miners?

2) Has somebody bought anything from you and can vouch?

3) Do you ship to the Eastern Europe?

37  Bitcoin / Mining support / Re: S7 - Hardware & Software problem solving section! on: September 17, 2016, 04:36:47 PM
Hello!

So, here is my problem: recently I started noticing, that once or twice a day my s7 goes offline for no reason. My internet connection is absolutely fine, and the miner keeps working in the void without submitting any share anywhere. I have to unplug and plug him again, so that he connects to network again.

Could you help me please, how to fix this?
